Alumina exports totaled 374,266 tonnes in Q3 2025, falling 5.3% from the previous quarter but remaining 12.9% higher year-on-year, reflecting mixed performance across operating refineries. Windalco shipped 98,548 tonnes of alumina, an 11.9% quarterly decline and 9.4% below Q3 2024, reversing part of its strong Q2 rebound. Jamalco accounted for the majority of exports at 275,718 tonnes, down 2.7% quarter-on-quarter but up 23.9% year-on-year, supported by improved output as shipments were severely constrained during this period in 2024 due to Hurricane Beryl’s damage to the refinery’s port facility.

Domestic alumina production totaled 352,255 tonnes in Q3 2025, down 3.2% from Q2 but 2.0% higher YoY, as the industry’s two active refineries operated at an average rate of 37.8% capacity. The decline was led by the Jamalco refinery (operating at 77% capacity), which recorded a quarterly decrease of 3.2% to 270,269 tonnes, though output remained 8.1% above Q3 2024.

Crude bauxite exports totalled 433,810 tonnes in Q3 2025, down 9.2% from the previous quarter but 12.7% higher YoY. The quarterly decline reflected softer third-party sales to China, partially offset by increased shipments to the Gramercy refinery in the U.S., which helped sustain overall export volumes.

Total bauxite production (crude output plus alumina equivalent) reached ~1.47 million tonnes in Q3 2025, down 6.7% from Q2 but 8.8% higher year-on-year. The quarterly decline reflected weaker output across major producers following strong early-year performance.
